Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489046, here are decompositions:

23 + 2147489023 = 2147489046
29 + 2147489017 = 2147489046
127 + 2147488919 = 2147489046
139 + 2147488907 = 2147489046
179 + 2147488867 = 2147489046
433 + 2147488613 = 2147489046
467 + 2147488579 = 2147489046
487 + 2147488559 = 2147489046

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.22.

Address: 128.0.21.22
Class: public
IPv4-mapped IPv6: ::ffff:128.0.21.22

Public, routable address (assignable to a host on the internet).
